Pete Iorizzo, of the Albany Times-Union, reports the Minnesota Vikings have invited Siena basketball player Michael Haddix for a tryout to be held the first week of May. Haddix is a former center on the Siena men's baseketball team. The Vikings have told Haddix they want to see him lift weights, run pass patterns and catch a few passes. If the workout goes well, the team might ask him to stay for a more extended workout. The team told Haddis they expect to work out three or four college basketball players to see if they can play tight end.
